Hi,When you pressed "submit" to post a reply to a topic, there used to be a warning that someone else had replied to the topic since you started your reply. A couple of times recently this hasn't worked. The first time I thought it was just me not paying attention, but it's just happened again and there had been 2 replies posted in the time i took me to compose my masterpiece. Although the recent ability to delete your posts solves this issue!
